Who are the children in the ancient philosophers' hall?

The children of Baizitang were abandoned by their parents and could not afford to raise them.

Baizitang refers to the place where children abandoned by their parents and unable to raise them are sent to temples or charities for refuge. Children can't bear the responsibility of raising because of family poverty, parents' death or other reasons. The establishment of the Baizitang aims to provide shelter and care for these children and give them the basic protection and care they need for their lives. This practice has played a certain role in social assistance in history, helping those helpless children get opportunities for survival and growth.
